Client side validation in struts using validation framework

Hi ,
am new to struts.....
I want to validate a simple login page using struts validation framework...
For that i created,
login.jsp ( contains html:errors and html:javascript and onsubmit)
LoginForm extends ValidatorForm
LoginAction
resource bundles
validation.xml ( required, minlength and maxlength rules for both fields)
struts-config.xml ( configured action mapping and form beans)
whats my problem is....
i will get error messages through server side validation...
i cant able to get the error messages using javascript i.e alert messages.
i seen the page resource in that all javascript functins are inserted.
on seeing the javascript error console... it shows
formName has no properties...............
exactly at this line
oRequired = eval('new ' + formName.value + '_required()'); //function validateRequired(form)

Thanks for your valuable reply.....
Ya of course what you said was correct....
I got error messages while submitting the form without any value....
error messages are displayed using the <html:errors/> tag (server side validation ).
But it fails to show the alert messages for those errors ( client side validation).
i inserted the <html:javascript formName="form bean name" /> tag in the bottom of my login jsp.....
on seeing the error console, it shows formName has no properties.
Could anybody help me to sort out this problem........

Problem in creating client side PDF with image using flex and AlivePD

I need a favor I am creating client side PDF with image using flex and AlivePDF for a web based application. Images have been generated on that pdf but it is creating problem for large size images as half of the image disappeared from that pdf.I am taking the image inside a canvas . How do i control my images so that they come fit on that pdf file for any image size that i take.
Thanks in advance

I am having a similar and more serious problem. It takes a
long time to execute, but even attaching a small image balloons the
pdf to 6MB plus. After a few images it gets up to 20MB. These are
100k jpeg files being attached. The resulting PDF is too large to
email or process effectively. Does anyone know how to reduce
size/processing?

Printing web page at client side

i want to print web page at client side . Page & printer settings are through coding. i tried using
DocFlavor myFormat = new DocFlavor("text/plain; charset=utf-16be","java.net.URL");
i found exception invalid flavor

If you are trying to print a web page on the client side, you have to use the browser's print function which can be invoked through JavaScript. What you are trying to do can't possibly work. Even if you weren't getting an exception, it wouldn't work. Any Java code in the JSP will have no effect on what happens on the client's machine.

Client-side UserTransaction

Ok,
          POJO client side. API code uses JNDI to find TransactionManager and determines that there are no current XA connection running so it uses JNDI to lookup javax.transaction.UserTransaction.
          It starts the transaction by calling begin()
          It calls some other code that sends a JMS message.
          It commits the transaction.
          end of story, eh.... no.
          I use JView 2004 to get performance data like transaction throughput and cannot see that a transaction was started and committed. To see that a transaction actually was started I use userTransaction.getState() after begin() and verifies that it is active.
          I then get the thread name after begin and just before the queueSender.send(....) code and it is the same.
          Finally, I verify with success that the transaction was committed.
          If I use a MDB to read the message from the queue I can see the transaction throughput in JView.
          Is it some bizarre I have forgot that a getStatus()==Status.STATUS_ACTIVE wouldn't catch or do you think JView cannot "see" client initiated transactions?
          Lars

My guess is JView cannot see the transaction, have you tried using the weblogic console to monitor the transaction.
          servers>monitoring>JTA
          you can then select to monitor the transaction by name, resource or inflight.
          Tell me how you get on.

Client Side Support for NTLM

Hi
I have been trying to read my mails from Microsoft Exchange Server by using java library developed by Various Software Products like Javamail,Mousetrap,Icemail,Jscape,JavaMail, and IPWorks.
On our server side we are having "Secure Password Authentication"(NTLM) in order to encode and decode mails, So we need to use the same Authorisation Mechanism on Client Side so that we can read mails from the Exchange Server.
( As Server Side Autherisation Mechanism should match with Client Side Autherisation Mechansim to read mails from Exchange Server)
On Client Side, I have tried using the software products that i specified above. All the above listed products are supporting CRAMMD5,PLAIN,LOGIN,DIGEST-MD5 Autherisation Mechanisms But, No one are supporting NTLM Autherisation.
As we have NTLM autherisation mechanism set on the server side, so i need to use the same Autherisation mechanism on client side too.
The current Exchange server version we are using is " 5.5.2654.50". I have also tried installing the Evaluation version of Microsoft Exchange server 2003 and checked whether it supports any other authentication other than NTLM. I found that, it is allowing me to use either "Clear Text" or "NTLM".
could anyone help me in providing any Software Product (Java Library) that supports "NTLM Autherisation" to read mails from Exchange Server.
Protocol that we are using - IMAP
I will be greatful if anyone can help me in this
thanks

The problem is that NTLM is a Microsoft proprietary authentication mechanism.
I believe there are some products in the JavaMail Third Party Products page
that support NTLM.

STRUTS: client-side validation in jsp using DynaValidatorForm

I am supposed to work on struts on as project and it is like learning a crash course and work the next day.
In Struts 1.1 enviroment, I am using DynaValidatorForm to create a bean form and then perform validation.
1. I write a DynaValidatorForm definition in struts-config.xml
2. I write xml for action so that when /getQuotes.do in invoked by a jsp form, the form data is put into the QuoteDetailsBean.
3. add the plugin script for ValidatorPlugIn
xml fragment from struts-config:
//form bean
<form-beans>
<form-bean name="QuoteDetailsBean" type="org.apache.struts.validator.DynaValidatorForm">
    <form-property name="forename" type="java.lang.String"/>
   <form-property name="surname" type="java.lang.String"/>
<form-bean>
</form-beans>
<action
        path="/getQuotes"
        type="com.kainos.quickquotes.struts.QQGetQuotesAction"
        validate="true"
        name="QuoteDetailsBean"
        input="/userform1.do"
        parameter="save"
        scope="session">
        <forward name="success" path="/pages/jsp/result.jsp"/>
        <forward name="back" path="/userform1.do"/>
</action>
<plug-in className="org.apache.struts.validator.ValidatorPlugIn">
     <set-property
         property="pathnames"
         value="/WEB-INF/validator-rules.xml,/WEB-INF/validation.xml"/>
</plug-in>Now I write a validation code for getQuotes.do. note that I can write the validation code with
<form name="QuoteDetailsBean"> but this form bean is shared by many jsp, so i am using the name of the action
(getQuotes) as the name of the form in the validation.xml.
So far this looks okay, as I am going by some example.
xml fragment from validation.xml:
<formset>
          <form name="/getQuotes">
             <field property="forename" depends="required,minlength">
                <arg0 key="QuoteDetailsBean.forename" />
                <arg1 name="minlength" key="${var:minlength}" resource="false"/>
                <var>
                   <var-name>minlength</var-name>
                   <var-value>2</var-value>
                </var>
             </field>
             <field property="surname" depends="required,minlength">
            <arg0 key="QuoteDetailsBean.surname" />
            <arg1 name="minlength" key="${var:minlength}" resource="false"/>
            <var>
               <var-name>minlength</var-name>
               <var-value>2</var-value>
            </var>
             </field>
</formset>Now I write the JSP. I use the <html:javascript> tag to allow front-end validation based on the xml in validation.xml.
The jsp code:
<%@ taglib uri="/tags/struts-bean" prefix="bean" %>
<%@ taglib uri="/tags/struts-html" prefix="html" %>
<%@ taglib uri="/tags/struts-logic" prefix="logic" %>
<html:html locale="true">
<head>
<title><bean:message key="welcome.title"/></title>
<html:base/>
<html:javascript formName="/getQuotes"
            method="validateForm"
            dynamicJavascript="true"
            staticJavascript="false"
            cdata="false" />
</head>
<body bgcolor="#FFCC9F">
<html:errors />
<html:form action="getQuotes.do" onsubmit="return validateForm(this);" >
Forename:</td> <td>��<html:text property="forename"/></td></tr>
<tr> <td>Surname:</td> <td>��<html:text property="surname"/></td></tr>
<html:submit value="Quotes" /></td></tr>
</html:form>
</body>
</html:html>Does this looks okay. I wrote so far based on some tutorials n help online.
Now when I open the JSP and then do a submit, there is no validation (I tried by submitting with empty forename and surname. I mean i could invoke the action class and the invoke class
redirects(forwards) to the appropriate path. so the code works fine except validation is not done
Q1. So what should i do more to get client-side validation?
What actually happens in client-side validation? does a pop up alert appears?
nothing happens so far in my case.
Q2. What should I do more for server side validation. Since the form is incomplete, what happens?
I thought the same form returns and the error messages are printed in the jsp page since i have the <html:errors />
tag just below the <body> tag.
The action class is pretty simple so far:
public class QQGetQuotesAction extends Action {
    public QQGetQuotesAction(){
public ActionForward execute(ActionMapping mapping,
             ActionForm form,
             HttpServletRequest request,
             HttpServletResponse response)
    throws Exception {
        DynaValidatorForm dynaform = (DynaValidatorForm)form;
        System.out.println("forename:"+dynaform.get("forename");
        System.out.println("surname:"+dynaform.get("surname");
        return forward=mapping.findForward("back");
}Please help me out. I think I am missing something which i need to do
thanks

I think the validations are to be declared on the form
name and not the action path.
Your formName is QuoteDetailsBean but your are using
the action path(/getQuotes) both in the validation
rules and the jsp tags. Use the formName on both the
places.
Also your html:javascript tag will not generate the
static javascript to validate the fields. For this you
will have to add code like below.
<html:javascript dynamicJavascript="false"
staticJavascript="true"/>
Other options is to set the attribute
staticJavascript="true" in your html:javascript tag.
Hope it helps.hi
staticJavascript="true" did the trick. :)
I think the validations are to be declared on the form name and not the action path.It is not necessary. You can declare the validation on the action class. This is essential if a form bean is shared by several JSPs having its own action class. This is as per as I read in a tutorial and it works.

Client Side Javascript Validation not Working in Struts 1.x version

hi,
I'm following the steps provioded in the below link for Javascript Client side validation but still it is not working.I'm struggling to get this work.
[http://www.visualbuilder.com/jsp/struts/tutorial2/pageorder/9/|http://www.visualbuilder.com/jsp/struts/tutorial2/pageorder/9/]
"The framework automatically generates the browser specific JavaScript and validate the data only at the client side."From the above statement i undertstand that framework itself generates the javascript function for validating the field mentioned in validations.xml file so that we dont have to explicitly write a javascript function for
validating the fields
(or)
Do we need to call an explicit function
Please need help on this.
I have followed all the steps mentioned on the above link but Client Side Javascript Validation not Working in Struts 1.x version....

Struts 2 Client side validation getting skipped.

I am doing a simple program using struts 2. Usually in struts2 bean class will be combined with action class unlike in struts 1.2. But for enhancing readability I made a seperate bean class and I reference it in my action class. But after seperating bean from action class Client side validation using xml is not happening. It is getting skipped. But server side validation inside execute() is happening. Will anyone please help me to find a solution to make client side validation run.
here are the different files.

I was trying to do it through creating a new validators.xml where I would redefine all struts built in validations and add de definition for my custom Validation (<validator name="checkUser" class="com.custom.CustomUserValidator"/>). Then I define the ActionClassName-action-validation.xml refering to my custom validator (checkUser). The com.custom.CustomUserValidator Class has to extend FieldValidatorSupport or ValidatorSupoort (depending on what kind of validation).
Ok that's it, this is the theory, now the custom validator (checkUser) is executed before my action but I don't know how to do it so that if the validation fails i return to the same page showing the error message to the user without having to execute the target action. Does anyone know how to do this????

Struts client side validation....

Hello all,
I am using struts client and server validation but only the server validation works. I tired looking around the forum but wouldnt find any similar problem.
I am getting value from the previous action class and i am able to successfully retrieve and display the value. I inserted the value in a object and pass over to my jsp. When i try inserting the validation, the server side works fine but i get nth on the client side. I viewed the source code of my jsp and the JAVASCRIPT is successfully inserted but no pop up when i leave the fill blank. Please advise mi..

Validating data in client side

Hi,
I'm developing a web application using Struts framework.
and my questions is, does the validate method int the ActionForm replaces the using javascript validation?
If I can do all the validations in this validate method, so does that mean that i'm not going to use JS at all?

Client side validation is usually a subset of the validation done on the server side (ie, server side duplicates the client side validation, and then some).
I usually only do some basic client side validation such as:
a textfield is null, but shouldn't be
a textfield should be in this format but isn't: mm/dd/yyyy
a textfield should be a number but contains a letter.
If these conditions occur, dont submit the form, pop up a warning dialog box instead.

Client Side Validation Problems

Hi,
When I use .Net validation controls on my aspx pages, the validation always executes server-side, even on IE clients, regardless of the EnableClientScript property on the validators.
If i hit the remote server directly, the validators work correctly - ie Client-side for IE and server side for all others.
So I assume that the remote server is unable to correctly identify the client browser as it's gatewayed via the portal. Does anyone know a way around this please?
Cheers,
Simon

Hi Jonathan,
Thanks for your reply.
I'm a .Net developer who's new to Plumtree development, so my appologies if i'm missing something obvious.
We're using the Broadcast Listener pattern, Portal Server v 5.0.3, Web Controls 2.1 and .Net Framework 1_1_4322_2032. We've generated the client script to support this version of .Net and installed in onto the ImageServer.
We have a menu portlet, which broadcasts a 'linkSelected' event on click of a menu item. Our main portlet is the listener and has an event handler that invokes a PTGetHTTPRequest call to one of a number of page for processing (depending on the menu item selected etc). This 3rd page contains all of the form fields, the validators and the validation summary.
When this aspx page has finished processing, there is an event handler in the 2nd page which scrapes the content of Response.ResponseText into a container <DIV> element on page 2 - ie dynamically building the html content with client script.
I've built a routine that can scrape this dynamically generated content of the <body> of the Listener portlet at this stage and when I examine this output, the validation js file and the inline __doPostback functions are all present.
I've done some debugging of the WebUIValidation.js file and although each individual validator is firing ok, it appears that the problem is manifesting itself in the ValidationSummaryOnSubmit_1_1_4322_2032()function. This function is called correctly, but it can't evaluate the Page_ValidationSummaries object.
This Page_ValidationSummaries object is defined and set within the inline script as follows :
var Page_ValidationSummaries;
function PTSetValidationSummaries_490()
{ [/b]
[b] var valsInput = document.getElementById('PT_VALIDATORS_SUM_490');
if(valsInput)
Page_ValidationSummaries = eval(valsInput.value);
else Page_ValidationSummaries = new Array();
and the PT_VALIDATORS_SUM_490 element is defined as :
<INPUT id=PT_VALIDATORS_SUM_490 type=hidden value="new Array(document.all['vsAll'])">
and the vsAll element is defined as :
<DIV id=vsAll style="DISPLAY: none; COLOR: red" showmessagebox="True"></DIV>
If I debug the WebUIValidation.js file, I can successfully evaluate document.getElementById('PT_VALIDATORS_SUM_490'), so I believe that the error occurs when the PTSetValidationSummaries_490()function executes (or perhaps PTSetValidators_490isn't actually calling it??).
I can't really debug this any further as I've now traced the error back to the inline script that's appended at runtime by the Plumtree environment.
Would it be possible for me to email this source code to you for inspection and comment please?
Cheers,
Simon

Af:query client side validation

Hello,
I have an application with 2 ViewObjects (based on SQL), each with its own ViewCriteria. I have 2 pages, each containing 1 of the ViewCriteria as af:query with results table. Each ViewCriteria has a number of fields, all f which are selectively required.
Now, when I go to page A, leave all fields empty and hit 'search', my fields get marked immediately as 'you need to enter at least one of the criteria'. No server request, just pure client validation, as you'd expect. Now we go to page B, doing exactly the same (empty fields, search). I see a lot of activity now, a server request, a query executed, and then a stacktrace saying 'at least 1 attribute is required'. In the front end, I also get a popup saying I have to enter at least 1 value.
Does anyone have any idea why the validation for both af:query components is different? Both ViewObject look the same to me, with same properties and attributes set.
Thanks in advance,
Stijn.

Thanks for the reply, Vinod.
The problem still persists, though. We're working with version 11.1.3 (where the issue should be fixed), and it doesn't happen every time. 8 out of 10 af:query-components we use go to the server before validating the input, resulting in a popup. The other 2 do client-side validation and immediately tell you to fill in the blanks (which is the behaviour we want)...
